Managed Voice / Extensions & Phone Numbers

Direct Inward Dialing (DID) Numbers

A DID (a phone number that rings straight into your system — see Glossary) can go to a specific person, department, menu, or even a marketing campaign. You can route and brand each one completely independently of your main published number.

How many DID numbers can a business have?

There’s no meaningful limit tied to the phone system — businesses commonly run anywhere from a handful of numbers up to hundreds, each mapped to its own destination, without needing additional physical phone lines for each one.

Does each DID need its own physical line?

No — all your DID numbers can run over the same underlying trunk (the connection to the phone network — see Glossary) and system. The number itself is really a routing address, not a separate wire.

Can a DID route straight to a menu or greeting instead of a person?

Yes — see Routing a Published Number Straight to a Menu for how you can point any DID at a specific auto attendant, department, or greeting rather than a single extension.

Are DIDs the same as toll-free numbers?

Not necessarily. A DID is typically a local or regional number, while toll-free numbers are a separate category with their own cost structure for the caller. See Local & Toll-Free Numbers for how the two compare.

Can we get new DIDs, or only use ones we already own?

Both — you can acquire new DID numbers in the areas you serve, or bring in numbers you already own from a previous provider. See Number Porting for how we move existing numbers over.
